Xultún is a large Maya archaeological site. Boasting a fairly large population, the site is located 40 km northeast of Tikal and 8 km south of the smaller Preclassic site of San Bartolo in northern Guatemala.
The site contains a 35 m tall pyramid, 2 ballcourts, 24 stele (the last of which, Stele 10, dates to 899), several plazas, and 5 aguadas (water reservoirs).
Xultún is the largest-known Classic Maya site that has yet to be archaeologically investigated.
Nearby sites include Chaj K’e’k Cué, a site believed to be the residential area of the Xultún elite, containing an 8 meter tall palace, Isla Oasis, and Las Minas. These later sites contain large limestone quarries. The site of Xultun includes a recently discovered mural with Late-Classic maya calendar computations. The computations contradict the New Age belief that the Maya thought the World would end in 2012.
